LUZON C. ENGLISH, OF CATON, NEW YORK, ASSIGNOR TO I-IIMSELF, AND GALUSHAM. ANGIER, OF WASHINGTON, DISTRICT OF COLUMBIA.

STUMP-EXTRAGTOR.

Specification of Letters Patent No. 27,949, dated April 17, 1860.

T o all whom 'it may concern:

Be it known that I, LUZON C. ENGLISH, of Caton, in the county of Steubenand State of New York, have invented a new and useful Improvement inStump-Extractors; and I do hereby declare that the following is a fulland exact description thereof, reference be ing had to the accompanyingdrawings and to the letters of reference marked thereon.

The object of my invention is to construct a stump extractor adapted topulling stumps, either on level ground, side hill, in orchards, nearfences or buildings, and to perform the work in the most convenientmanner.

My invention or improvement consists of a peculiar arrangement of thegears in connection with removable legs of peculiar construction andprovided with adjustable rollers.

In the accompanying drawings Figure 1. is a top View of my stumpextractor with the legs removed. Fig. 2. is a side view of my machinecomplete; Fig.v 3. a roller detached.

The frame A, Fig. 2, is usually supported on four legs B, secured bybraces C, and provided with foot pieces D, and adjustable rollers E.

When in operation the machine commonly rests upon the foot pieces D, theadjustable rollers E, being employed only for supporting the machine inmoving from place to place. The machine hoisted upon these rollers isbrought into proper position and the chain F, attached to the stump tobe extracted. Then the shaft G, is turned by a horse in the usualmanner, thus setting the screw shaft H, in revolution. The screw (see indotted lines Fig. 2.) of this shaft gearingv into the two spur wheels I,and K, sets the latter in motion and also, the axles L, M. These axlescarry two gear wheels O, P. Both the spur wheel K, and the gear wheelI), are fixed so as to turn with axle L, but the wheels I and O, areloose upon the axle IWI, and may be' fixed by two clutches N, and Q.When both clutches are released the axle M, turns independently, whichis very convenient in unwinding the chain F. The chain being fastenedupon the stump,

as above described, and the horse started, the wheel I is fixed by theclutch Q, until the stump is started, then the wheel O, is also fixedbringing into operation the wheels, K, P, O. The speed of the machine isthus increased and the operation of hoisting the stump is hastened. Thisdouble gearing affords great power at first while starting the stump andincreased speed after the stump has been loosened and thus facilitatesthe whole operation.

In situations where the horse cannot walk around the machine, as inorchards, near buildings etc. the shaft G, is removed and the horse isattached to the rope R, upon wheel S, Fig. l. This wheel sets the shaftT, and bevel gear wheel U, in motion and by means of bevel gear wheel V,operates the screw shaft H, and thus the whole machine. By the use ofrope R, the horse can travel off in a straight line instead of passingaround the machine in a circle as with the shaft Gr. When the rope isemployed it will be necessary to anchor the machine to prevent thelatter from sliding or being dragged horizontally. This may be done by achain attached to the hook "W, and fastening the machine to anotherstump or fixed object. The wheel S, may be removed when the shaft Gr, isemployed. i

Fig. 3 represents a side view of one of the roillers E, and the ratchetbar and half ratchet 'wheel by which the machine is hoisted upon theroller. By placing the hand on lever Z, the ratchet wheel X, and theratchet bar J, are easily operated thus elevating or depressing thewheel E, atpleasure. v

The form of my machine may be somewhat varied without departing from myin vention.

I ldo not broadly claim the use of a screw shaft operating a spur wheel.

Having thus fully described my inven tion what I claim and desire tosecure by Letters Patent of the United States is:

1. The above described stump extractor provided with two sets of gearingconsisting of shafts L, M, with their spur wheels, cog

yWheels and clutches, all arranged and operated substantially as setforth for the purposes described.

2. I claim the use of the Wheels S, and U, 5 in combination With thedouble gears above claimed substantially as described for the purposesspecified.

3. I claim the adjustable Wheels E, in combination with the foot piecesD, substantially as described.
